What is pulmonary embolus?

A pulmonary embolus is most often caused by a blood clot in a vein, especially a vein in the leg or in the pelvis (hip area). The most common cause is a blood clot in one of the deep veins of the legs. This type of clot is called a deep vein thrombosis (DVT).

Pulmonary Embolism

A pulmonary embolism (PE) is a blood clot in the lung. It usually comes from smaller vessels in the leg, pelvis, arms, or heart. When a clot forms in the legs or arms, it is referred to as a deep venous thrombosis (DVT). The clot travels through the vessels of the lung continuing to reach smaller vessels until it becomes wedged in a vessel that is too small to allow it to continue farther. The clot gets wedged and prevents any further blood from traveling to that section of the lung.

Pulmonary Embolism

Pulmonary embolism is a condition that occurs when one or more arteries in your lungs become blocked. In most cases, pulmonary embolism is caused by blood clots that travel to your lungs from another part of your body most commonly, your legs.

Pulmonary Embolism

Pulmonary (PUL-mo-ner-ee) embolism (EM-boh-lizm) is the sudden blockage of an artery (blood vessel) in the lungs by an embolus. An embolus is usually a blood clot, but may also be fat, air, or tumor cells that are in the blood stream. With a pulmonary embolism, a blood clot may break loose from the blood vessels of the legs. The clot goes to the lungs where it plugs or blocks a blood vessel. The embolism can cut off the blood supply to that part of the lungs. Pulmonary embolism is a serious condition. Chances of survival are better with early diagnosis and treatment.

Outlook (Prognosis)
It is difficult to predict how well a patient will do. Often, the outlook is related to what put the person at risk for pulmonary embolism (for example, cancer, major surgery, trauma). In cases of severe pulmonary embolism, where shock and heart failure occur, the death rate may be greater than 50%.

Preventing deep venous thrombosis (DVT) is very important, especially in people at high risk. To help prevent DVT, move your legs often or take a stroll during long plane trips, car trips, and other situations in which you are sitting or lying down for long periods of time. Walking and staying active as soon as possible after surgery or during a long-term medical illness can also reduce your risk.

Emergency treatment and a hospital stay are often necessary. The aim is to prevent new clots from forming. Oxygen therapy may be required to maintain normal oxygen levels. In cases of severe, life-threatening pulmonary embolism, treatment may involve dissolving the clot and preventing new clots from forming. Treatment to dissolve clots is called thrombolytic therapy. Clot-dissolving medications include: Streptokinase, t-PA. Treatment to prevent clots is called anticoagulation therapy. Such drugs...
